Abstract
The present invention provides a wall for a package comprising: a) an outer set of one or more layers 1-4, and b) an inner set of one or more layers 5-6, which layer or the outermost layer 5 of which comprises a composition containing a polymer and having oxygen-absorbing characteristics, in which i) the outer set of layers, if separated from the inner layer and in the absence of oxygen-absorbing characteristics in any of the layers or in the layer forming the set, would have an oxygen-conducting capacity not exceeding 1.5 cm3/(m2 atm day); ii) the inner set of layers, if separated from the outer set and in the absence of oxygen-absorbing characteristics in any of the layers or in the layer forming the set, would have an oxygen-conducting capacity of at least 2.0 cm3/(m2 atm day); and iii) the inner set of layers, if separated from the outer layer, would have an oxygen-conducting capacity less than the conducting capacity of at least 1.0 cm3/(m2 atm day) specified in ii by virtue of the oxygen absorption at least in the layer specified in b. In a preferred combination, one of the outer layers 3 is of metal, and the composition in the outermost of the inner layers 5 absorbs oxygen by metal-catalysed oxidation of an oxidiseable organic compound thereof. The wall is suited to packaging purposes with an inner set of layers applied to the product, where there is a particular requirement for absorption from the head space, that is to say the space between the packaging and the actual contents of the packaging. <IMAGE>
